Li Mengxi was about to leave, but his younger brother held him back and refused to let him go.

The younger brother who was sick at this time was as weak as a kitten, "Brother, what are you doing? I'll go too." The younger brother's voice was forced, and he looked at Li Mengxi with eyes that couldn't open because he was afraid that Li Mengxi would leave.

Li Mengxi's absence made his younger brother afraid.

"Little brother, let me go get some medicine for you."

Li Mengxi took away his brother's hand, stood up, and looked at Liu Bei, "Xuan Degong, help take care of my brother."

After saying that, Li Mengxi hurried out of the tent.

Li Mengxi asked Liu Bei to take care of his younger brother, but he didn't know that in Liu Bei's eyes, he, Li Mengxi, was also a baby who needed to be taken care of.

It's dark outside, what should I do if I get lost?

"Yun Chang, look at Xi'er."

Liu Bei ordered Yunchang to follow Li Mengxi.

Guan Yu then followed Li Mengxi out of his tent.

As the saying goes, caring leads to chaos. Li Mengxi walked out of the tent with his head down and walked a long way before he remembered that he didn't know where to find wine.

Li Mengxi then turned around and prepared to ask Liu Xuande for a drink.

Turning around, there was a bang, and Li Mengxi bumped into someone.

Just as he was about to fall to the ground, a strong hand grabbed Li Mengxi.

"Ah, Xi'er, I didn't hit you, did I?" Guan Yu said apologetically.

Li Mengxi looked up at Guan Yu and was speechless. Did he hit me?

"Brother Guan, I still don't have any wine. I want the wine to be useful."

Li Mengxi called Guan Yu and Guan Erge.

Guan Yu agreed naturally, not realizing that there was any inconsistency.

"Yes, I'll get it. You can return it to your account and wait."

Li Mengxi went back to his tent.

When he returned to his account, Li Mengxi saw Liu Bei sitting on the bed, holding his little brother in his arms, and his little brother was being quietly checked for pulse by two doctors.

Liu Bei is very good at coaxing children.

Seeing his younger brother Ansheng, Li Mengxi stopped going to his younger brother's place for the time being.

Sitting next to the low table, Li Mengxi stared at the grain of the wood on the low table in a daze.

Think carefully about the process of distilling wine.

Distilled wine is based on the principle that alcohol and water have different boiling points. The alcohol is heated to evaporate, and then the alcohol vapor is condensed into alcohol liquid through the condensation pipe.

This achieves the purpose of purifying alcohol to obtain high-strength liquor.

Heating is not a problem. The wine jar can be hung up, a fire is built underneath, and the wine jar can be heated directly.

Then, how to collect alcohol vapor.

Li Mengxi's brows were deeply furrowed.

A sealed structure is required, otherwise, as soon as the wine is heated, all the alcohol vapor will escape.

At this time, Li Mengxi suddenly discovered that distilling alcohol seemed to be such a simple thing, but in actual operation, it was not simple.

I don't know if bamboo pipes will work.

Bamboo tubes are fine for draining steam, but bamboo tubes are not metal and the condensation effect is not good.

Moreover, the sealing area of ​​the wine jar must be sealed before distillation.

"How about using mud?" Li Mengxi said to himself.

"What mud? Xi'er, I brought you some wine."

Guan Yu held two jars of wine in his arms and placed them on a low table.

Li Mengxi thought of using mud to seal the mouth of the wine jar, but Li Mengxi found that he couldn't even play with mud.

Mud is easy to find. It is everywhere, even under your feet. But after taking a look, you can see how to use the dry and dirty soil under your feet.

Li Mengxi had no choice but to ask Guan Yu for help.

"Brother Guan, I want to dig some yellow mud, mix it with water, and seal it on the wine jar."

Li Mengxi looked at Guan Yu and said.

Guan Yu was confused when he heard what Li Mengxi said.

Guan Yu stroked his long beard and looked at Li Mengxi with a surprised look, "Xi'er, this wine jar is topped with yellow mud."

Li Mengxi shook his head, "I want to find a thin bamboo, put it on the wine jar, and then seal the thin bamboo with yellow mud."

The more Guan Yu listened, the more confused he became.

"Are you useful?" Guan Yu asked.

"It works." Li Mengxi nodded.

"Wait a minute, I'm going to dig some up and bring them back."

Guan Yu was also very kind to Li Mengxi. When Li Mengxi asked for mud, Guan Yu had to go dig it all night.

If Guan Yu's own son talked about playing in the mud in the middle of the night, Guan Yu might slap him.

Just play in the mud and dig it out yourself.

"By the way, we also need a thin bamboo tube." Li Mengxi reminded.

"Okay, let's find them together." Guan Yu smiled and got up to look for them.

After Guan Yu left, Li Mengxi still had not figured out how to distill the complete distillation process under today's extremely limited technical conditions.

If you use bamboo, even wet yellow mud will have a good sealing effect, but if a straight bamboo stick is inserted into the wine jar, the alcohol vapor will enter the container?

Water bag?

It seems that the water bag is not very good. If the bamboo is placed vertically on the wine jar, and the water bag is placed on the bamboo, the alcohol can be collected, but all the alcohol will flow back.

If necessary, curved guide tube.

Where to find bent pipe?

The only diversion pipes that can be found that are barely usable are bamboo pipes. Where can I find bent bamboo pipes?

Otherwise, use two sections of bamboo pipes and find a way to connect them in the middle.

For example, yellow mud connection?

The yellow mud is so soft, how to connect it, Li Mengxi frowned into the Chinese character "Sichuan".

Distilling alcohol is so difficult.

At this time, I suddenly heard my brother crying.

"Don't prick me, don't prick me!" the younger brother cried, resisting acupuncture treatment.

"Xiao Zhuan, just two injections will heal you. It doesn't hurt. Be good. You'll be fine in a while." Liu Bei hugged Xiao Zhuan and coaxed him.

Without letting Li Mengxi come over, Liu Bei coaxed him for a while. Although Xiao Zhuan was very scared, he still closed his eyes and let the old man give him acupuncture.

Li Mengxi smiled when he saw it.

Without the actual objects, there was no way to test whether the bamboo tubes worked well, so we had to wait for Guan Yu to find the mud and bamboo poles.

But he said that in order to find mud for Li Mengxi, Guan Yu went out with a torch and the Qinglong Yanyue Sword.

After walking a hundred steps outside the tent, shining torches everywhere, I saw a loess hill, where there was fine yellow mud.

Guan Yu came to the mound, holding a torch and a knife in one hand, using the knife as a shovel. With a shovel on the ground, the powerful and heavy Qinglong Yanyue cut into the earth.

Taking advantage of the situation, he stepped on it and pried it up, and a large piece of loess was lifted up.

Afraid that Li Mengxi would not have enough, Guan Yu dug a lot more soil.

Then, he wiped the blade of the sword with his sleeve, stuck the torch on the ground, picked up the loess on the ground, hugged it with the hem of his clothes, and took a lot of loess back to Li Mengxi.

When returning to the camp, he met a patrol sergeant on the road. He happened to see a sergeant holding a bamboo spear, so Guan Yu asked for the bamboo spear.

Li Mengxi was in a daze when he saw Guan Yu coming in from outside the tent. Li Mengxi was surprised that Guan Yu came back wrapped in soil.

Thinking that Guan Yu was so interested in his impromptu idea, Li Mengxi was moved and hurriedly stood up to greet him.

"Xi'er, I've found the yellow mud, what else do you need?"

When Guan Yu came over, the yellow mud wrapped in his clothes fell onto the short table with a crash.

Li Mengxi thought of a way to connect the two bamboo poles.

Use linen strips as the inner lining, connect the bamboo poles with linen cloth, and then paste a layer of yellow mud on the outside of the linen cloth.

In this way, there is a curved air duct.

To collect alcohol, use an empty wine jar.

Because of the lack of condensation equipment, Li Mengxi had already thought of a way when Guan Yu did not come back.

Throw some relatively cold things into the empty wine jar, and then, after the alcohol flows into the empty wine jar through the air conduit, the alcohol vapor will condense into alcohol liquid when it encounters cold.

As for the things used for condensation, Li Mengxi thought that metal armor plates, copper coins, or metal arrowheads could all be used.
